(ctenophora/comb jelly?)

I posted this here and not hitchhikers because I just thought it was interesting. Found these little jelly lookin guys in my copopod jar, they have 4 tentacles/corners on the medusa under a magnifier. They swim like jellyfish.

Sorry for the bad focus..

Hydroid jellyfish, a type of medusa
 
Are you going to keep it?
From what I'm reading they're harmless to the tank, but probably aren't good for growing copopods ha. The jar was just an experiment to see if I could breed copopods anyway..surely they'll get water or filtered by the sock.
